Modelling and ZVS control of an isolated three-phase bidirectional AC-DC converter
Year: 2013
Type: conference-paper
Abstract: This paper presents an isolated three-phase bidirectional AC-DC converter with a novel modulation strategy that enables Zero-Voltage-Switching (ZVS) for all switches over the whole AC line period. The AC-DC converter allows the direct coupling of a three-phase AC system with a DC port applying a single high-frequency transformer. A novel modelling approach for the power flows and the derivation of the control variables under ZVS conditions are provided. The design of components including loss models and simulation results of a 11kW electric vehicle battery charger to connect to the 230Vrms, 50Hz mains considering a battery voltage range of 380V to 540V validate the theoretical analysis.
